Replica of a Sharps derringer. Made in Italy by Uberti { Italy }. They are neat little guns and fun to play with, most , if not all, were in .22 short. They have some value here in the states ( maybe a hundred dollars ) but in your location, well, don't know. They are not a antique or historical firearm and have no collectors value as a old west firearm. Perhaps a fishing trip is in order? It would be a shame to accidentally drop it overboard but if you have no other options. Added: Yes it is a firearm.
